A desktop technician is repairing a Windows workstation that fails to boot into the operating system, displaying an error stating that the Boot Configuration Data file is missing required information. The technician boots the system into the Windows Recovery Environment (WinRE) and opens Command Prompt. Which command should the technician execute to scan all connected disks for compatible Windows installations and rebuild the BCD store?

  1. bootrec /rebuildbcdCevap
  2. B
    bootrec /fixmbr
  3. C
    bootrec /fixboot
  4. D
    sfc /scannow

Cevap

The bootrec /rebuildbcd command should be executed because it completely scans all connected disks for Windows installations and rebuilds the Boot Configuration Data store.
Executing bootrec /rebuildbcd scans all connected disks for installed Windows operating systems and allows the technician to select which installations to add to the BCD store, resolving missing BCD errors.

Adım Adım Çözüm

1
Identify the root cause of the system startup failure
The system cannot boot due to missing or corrupted Boot Configuration Data (BCD).
The displayed error message explicitly identifies a BCD failure.
2
Select the correct bootrec utility switch in WinRE Command Prompt
Executing bootrec /rebuildbcd scans all drives and prompts to add missing Windows installations to the BCD store.
The /rebuildbcd flag is designed specifically to reconstruct damaged or missing BCD entries.
